I have to haul my engineering books around with me, no real choice there but I have adopted e-books for pleasure reading.
I use a desktop seedbox to get content found on piratebay.se via µ-torrent.
Then I use Calibre E-Book Management (free on C-Net) and convert all content to .mobi format. Calibre on the desktop sends .mobi books to its client installations on my Kindle Fire and my Galaxy SII over my wireless network. I use the native Kindle reader on the Kindle Fire and I use Cool Reader on the Galaxy SII.
